Some Thermodynamic Properties of Formic Acid.

Ideal gas thermodynamic properties of methanoic and ethanoic acids

“…His reported values for HCOOH(g) are in error with or without the 0 K additional correction term. Our calculated entropy value So (HCOOH, g 298.15 K) = 59.483 cal K-l mol-1 is in agreement with the reported third law values, 59.44 ± 0.1 cal K-l mol-1 by Waring [48] and also 59.30 ± 0.3 cal K-l mol-l by ' Halford [99]. The statistical entropy for methanoic acid dimer (g) has been reported as 83.35 cal K-I mol-l [48] and 82.89 cal K-l mol-l [125], respectively, while our recommended value is 79.51 cal K -1 mol-I.…”

“…The third law So (HCOOH, g, 298.15 K) was obtained as 59.44 cal K-l mol-1 by Waring [48]. Assuming there was random orientation in the crystal, he added (112) R In .…”

“…Table 3 summarizes the reported values of V9 and V by numerous investigators to date. The values given by Waring' [48] were selected initially so that the calculated statistical entropy would be in reasonable agreement with the third-law. entropy.…”

Efficient Catalytic Decomposition of Formic Acid for the Selective Generation of H2 and H/D Exchange with a Water‐Soluble Rhodium Complex in Aqueous Solution

“…[11] Such a liquid is suitable for easy transportation, handling, and storage compared to other methods. [16] Simple catalytic decomposition of formic acid at the site of use yields H 2 . The side product is CO 2 , which can be recycled by repeating the reduction to formic acid.…”

Thermochemistry and the Thermodynamic Properties of Substances

“…In many cases use is made of existing equilibrium or thermal data to choose values of t:.. Hoo for reactions and the calculated equilibrium constants are tabulated. Waring (196) has reviewed the thermodynamic properties of formic acid. Keller & Johnston (197) calculate an approximate entropy for decaborane.…”
